building olsen fast-fire kiln

I'm considering building a olsen fast-fire kiln with hard brick. I want to
soda-fire in it. I was wondering if anyone out there has ever built one
and if they may have a copy of their supply list and any photographs. I
have Fred Olsens Kiln Book, but was seeing if I could be better prepared.
Thanks, Mark

Mark,

I supervised the building of The Clayarts Guilds fast fire kiln in Helena,
Montana. Same design as in Olsens book.

I never was able to fire it before the board changed it to a gas kiln.
Also it is made out of soft brick. Josh at the Archie Bray Foundation said
they had one at MSU and it took longer to fire made out of hard brick.

This month's Ceramic Monthly Mag has this design and shows excellent
results.

It amazes me that this type of kiln can reach cone 10 in 4 hours!!!

I could probably help with more details on the design.

I have built lots of kilns. Had a woodfired cross draft that you could fire
three life size statues of people in. It did take about 18 hours to fire to
cone 10-11. It was lined with hard brick on the inside and the outside layer
was soft brick.

Where are you located?

I have a very large supply of a material called KALO made by Owens Corning
that they use on nuclear subs for the piping. It was surplus that a friend
bought on the west coast. It is still in the boxes brand new.It is a
wonderful insulater and I want to experiment with it on the exterior of a
wood fired kiln. It definately is cheaper than soft brick. It was given to
me!!!! I had a cone 10 test ran on it. It shrank a lot however on the
outside layer it may work very well.


Les in the Rockies!
